HYDRQGARBON-BURNEH.

SPECIFICATION forming part of Letters Patent No. 768,352, dated August 23, 1904, Application filed September 28, 1901, Serial No. 76,941. y(No model.)

T0 all whom it may cfm/cern,.-

Be it known that I, PHILIPP ULMANN, a citizen of the Republic of Switzerland, residing at Zurich, in Switzerland,havc invented new 'and useful Improvements in Hydrocarbon- Burners, of which the following' is a specilication.

The present invention has reference to hydrocarbon-burners, and relates more especially to burners in which a liquid hydrocarbon is vaporized and burned: and its object vis to provide a burner of this kind in which the initial vaporization of the hydrocarbon is efl fected by means of an auxiliary open iiame until constant vaporization is established,

x when the auxiliary flame extinguishes and the generated vapors are used in part to .sustam constant vaporization.

In order to make my invention more readily understood, I have illustrated it on the ac.- companying sheet of drawings, in which--l Figure l represents a burner according to my invention in vertical section. .Fig p 2 shows a sectional elevation of a modified detai Referring to the drawings, a is the feed or j supply pipe for the liquid hydrocarbon, opening into the vaporizing-tube the lower part of which is surrounded by a dished disk c.

The upper end of this tube is closed by av nozzle d, provided with a central opening of relatively small diameter.- Within the vaporizing-tube is centrally arranged a regulatingneedle e, gas-tightly extending through the cylindrical extension-piecef and secured in set-screw g. The upper end of the member vL runs out into a sleeve c, provided with a i surrounded by thebell-shaped extension g of atrebly-bent tube m. The extension q, which is closed by the bottom ring u,'is provided with air-inlets n. The tube mis bent lacross the main burner-head 0 and communicates with the latter by the port p. Below the bot- The mode of, working of the described api paratus is the following: By turning the handleZ the regulating-needle e is lowered within the nozzle d, permitting liquid hydrocarbon to enter through tube a into the vaporizingtube b from a supply source. (Not shown in the drawings.) Into the dished disk c alcohol or coal-oil is poured and ignited, with the effect that the vaporizing-tube is heated and part of the inclosed hydrocarbon is vaporized. This gas issuesfrom the nozzle 0l into the tube m gandentrains atmospheric .air kthrough the openings nf Air and vapors mix within the tube m, and the largest part of the mixture passes through the port p into the burner-head 0, where it is ignited in any suitable manner. The rest passes through the port o into the chamber o and escapes thereout through the openings s, when it is ignited by the auxiliary iiame burning in the dish c. The iiame of the main burner superheats the mixture of vapors and air passing through the tube m, so that the mixture enters the burner-head in a highlyinfiammable state. The constant vaporization is sustained after the auxiliary flame has gone out by the fiames issuing from the fine openings s in chamber r. By turning the handle Z back again more or less the liame of the main vburner can be regulated, and by wholly closing the nozzle-opening by means of the needle further vaporization is suspended and the lamp extinguished.

What I claim, and desire to secure by Letters Patent, is-

l. A hydrocarbon-burner comprising a vapor-feed tube having substantially the form of an inverted U, a horizontal tubular extension from the end of one of the tube-legs, a burner on said extension, a mixing-chamber at the end of the other tube-leg, a heating-chamber below the mixing-chamber, a vaporizing-tube extending through said heating-chamber into the mixing-chamber and means for supplying vapor to said heating-chamber from the vaporfeed tube, substantially as set forth.

2. A hydrocarbon-burner comprising a vapor-feed tube having substantially the form of an inverted U, a horizontal tubular extension from the end of one of the tube-legs, a burner on said extension, a mixing-chamber at the end of the other tube-leg, a vaporizing-tube extending into said chamber, a vapor-burner surrounding said vaporizing-tube below the mixing-chamber said burner in communication with the horizontal extension of the vapor-feed tube, for the purpose set forth.

3. A hydrocarbon-burner comprising a vapor-feed tube having substantially the form of an inverted U, a horizontal tubular extension from the end of one of the legs of said tube, a burner on said extension about midway between the legs of the tube, a mixing-chamber at the end of the other leg, a vaporizing-tube extending into the mixing-chamber, a vaporburner surrounding said tube below said chamber, said burner in communication with the aforesaid horizontal extension, for the purpose set forth.

4. A hydrocarbon-burner comprising a vapor-feed tube having the form of an inverted U, an enlarged horizontal extension provided with a burner at the end of one of the legs of said tube, a mixing-chamber at the end of the other tube-leg, and a heating-chamber below said mixing-chamber and in communication with the aforesaid horizontal extension; in combination with avaporizing-tube extending through the heating-chamber into the mixingchamber andatubular burner in said heatingchamber concentric with the vaporizing-tube, substantially as set forth.

5. A hydroearbon-burner comprising a vapor-feed tube in the form of an inverted U having an enlarged horizontal extension at the end of one of its legs and enlarged vertical extension at the end of the other leg, the lastnamed extension provided in its upper part with air-ports, and below the latter with a combustion-chamber in communication with the aforesaid horizontal extension; in combination with a vaporizing -tube extending through said combustion-ehamber into the upper part of said vertical extension, a vaporjet nozzle at the upper end of said vaporizingtube, and means to supply liquid fuel to the latter, for the purpose set forth.

6. A hydroearbon-burner comprising a vapor-feed tube substantially of the form of an inverted U having at one end a horizontal burner extension and at the other end a mixing-chamber, a support for said tube and a dish for liquid fuel projecting from said support; in combination with a vaporizing-tube extending through said dish into the mixingehamber, a heater for said wiporizing-tuhe between the dish and mixing-chamber and means for supplying vapor from the vaporfeed tube to said heater, for the purpose set forth.

In testimony whereof l have signed my name to this speeiiication in the presence of two subscribing witnesses.
